Abstract
An integrated demodulator tuning circuit () receives differential currents at input terminals () and provides an AFC signal at an output terminal (). The AFC current characteristic has a dead band () in the output current generated when the integrated demodulator tuning circuit () operates under the condition where the difference between the currents supplied at the input terminals (and) is at or below a set threshold value. The set threshold value is determined by the relative sizes of the transistors (andand) that form the current mirrors connected to the input terminals ().
